| Outline of Final Research Achievements |
To facilitate natural ventilation design for mid- to high-rise office building, this work first organized a generic database of wind pressure coefficient of the buildings in a city, and evaluated error of the natural ventilation rate estimated by using the database. Second, a parametric study regarding natural ventilation opening area and resistance of the flow path is performed, which can be used for simplified estimation in the preliminary design phase. Then, tendencies of indoor distribution of several quantities are analyzed by computational fluid dynamics for each type of natural ventilation inlet opening. Finally, the practical problems under the actual operation of natural ventilation building is clarified based on field study of high-rise office building where natural ventilation system was installed.
